Contact sheets are interesting, showing the "flow" of a particular session.. and possibly something of an insight into the photographer's selection process. Patric Demarchelier's web site includes a number of his contact sheets.
One word of caution - the images here are NOT "finished" and they are not meant to - and do NOT represent my "best" work -- they only illustrate "starting points" for the darkroom work.
In one of the critques posted to my "Untitled", in the Critque gallery, something was said to the effect of "an unhappy, tense model". I don't think so ... you might draw your own conclusios from the contact sheet -- one of eight from that session.
